DSPE-PEG2000-NHS
CAT. NO. DC66110
DSPE-PEG2000-NHS is a reactive PEGylated phospholipid for liposome surface modification and bioconjugation research. It combines a DSPE lipid anchor, a PEG segment and a terminal NHS ester for attachment to amine-containing molecules.
The molecular weight is an average value for a polymeric material. The structure shows a variable PEG repeat unit; it does not define a single oligomer.
